1/2" Schedule 40 PVC have been running around 180’ of it for years and even in the cold Mi weather. I run it around 150 psi and have never had a problem.
Does anyone have links to a good source of the PEX line and fittings? I’m having trouble finding 3/4" sized line. Preferably in Red or White, i just can’t stand the Blue color, haha.
gotta say it…AMAZON…

Amazon = 99% cheap chinese garbage… most of the time they push the chinese junk to the front page (higher profit margin), so if you search for generic airline, or generic PEX, all the results that come up are untrustworthy… and I kept getting blasted with that Maxline kit, just couldn’t get away from it…
However, after a lot more reading/research, i finally found a trustworthy name-brand PEX (Sharkbite), available in White, that looks like a good purchase:
I get the Sharkbite PEX at Lowe’s. They have red, white or blue in 50’ rolls and all of the fittings you might need. I started out using the push on fittings, but they got so expensive that it was worth getting the crimping tool and getting the crimp on ring style.

Did you use the Brass or Plastic push-on fittings? I only need maybe ~7 fittings, so i was going to go with the Brass ones for quick/easy install. Are the crimp-on removable, or do you have to cut the line?
How did you layout your air drops? I’m considering just using a T to NPT to disconnect. But it seems kind of jenky.
I used the brass ones. They are removable with the little plastic C shaped tool they sell for them. I used the straight PEX to NPT fittings and then a reducing fitting down to 1/4 for the air hose connection. On my newer drops with the crimp on I used these at the air line screwed to the wall. https://mobileimages.lowes.com/productimages/ef9b25a2-3870-4f7b-a3ba-894d2b911212/07825492.jpg?size=mpdhi

Took all of the advice from here and piped my whole shop. Very grateful to everyone on the forum who gives advice and suggestions.
For anyone interested, here is a detailed overview of my new system.
P.S. I have another 3-stage dryer right before the Plasma cutter. Just didn’t want to show my expensive CNC machine to the public.
hopefully this isn’t too off topic, but I’m using 1/4 connectors from the compressor through a 2 stage dryer, a motor guard drying thing and into the razorcut 45. Will 1/4 have sufficient air flow for the plasma cutter? or do i have to go through and do all 3/8 connectors? It’s a brand new 60 gal dewalt so that wont’ be the limiting part
The standard 1/4" air fitting seem to work just fine.

Motor Guard is not a ‘drying thing’. It is a very fine particle filter. If you’re expecting it to dry, it will until the filter gets wet (which is pretty soon after you try to use it as a dryer).

True, but it’s likely incredibly effective at condensed moisture capture.
@AHBuilt drying the air before the motor guard m60 is ideal. If you have condensed moisture in your system by the time it reaches the motor guard you need to rethink your air system.

Just to make things clear you should definitely dry your air before it reaches the m60 motor guard.
